Willdenow's description of this species is pretty full, and includes' 

 all the essential characteristics of our plant. 



8. DlPLAZIUJl MELANOCAtTLON, Sp. Nov. 



D. stipitibus nigris Icevibus angulatis; frondUnts glabris bipinnatis; 

 pinnis oblongo-lanceolatis attenuatis; pinnulis alternis sessilibus lan- 

 ceolatis acuminatis pinnatifidis basi truncato-cuneatis supra atro- 

 viridibus subtus pallidis, laciniis oblongis falcatis subacutis serrulatis ; 

 rhachi comrnuni flexuosa ; soris brevibus decussatis. 



Hab. Ovolau, Feejee Islands. 



Fronds large, 4 to 5 feet long, the divisions spreading, smooth on 

 both sides, of a much paler colour on the under than upper surface, 

 Upinnate. Pinnce oblong-lanceolate, attenuating into a sharply serrate 

 point. Pinnules alternate and sessile, lanceolate, acuminate, pinnatifid ; 

 the base truncate-cuneate. Segments oblong, falcate, subacute, serrulate. 

 Stipes and rhachis smooth and angular, of a dull black colour; the 

 main rhachis flexuose. Sori short, decussate. 



In habit and general aspect this very much resembles the D. arbo- 

 rescens of Swartz; but it is readily distinguished by its black, angular 

 stipe, its flexuose rhachis, and by the sharper and more attenuated 

 primary divisions of the fronds. 



9. Diplazium Arnottii. 



D. stipitibus Icevibus angulatis hinc sulcatis ; frondibus glabris bipin- 

 natis; pinnulis subremotis patentibus lanceolatis acuminatis pinnati- 

 fidis, laciniis ovato-oblongis subfalcatis obtusis crenato-lobatis ; soris 

 plurimis obliquis; indusio sospe binato, 



Asplenium diplazioides, Hook. & Am. Bot. Beech. Voy. p. 107. 

 Hab. Sandwich Islands ; frequent.
